To all whom. 'it nog concern: Y

Be it known that I, JAMES G. HEAsLE'r a citizen o4 the United States, resident of Detroit, county of Wa ne, and State of Michigan, have invente a new and useful Iiiipro' ement in Differential Gearing for Automobiles, of which the following is a specification, the principle of the invention bein herein explained and the best inode in whic I have contemplated applying that principle, so as to distinguish it from other inventions.

Illy invention has reference to a differential gear for automobiles, and particularly to the housing connections therefor, which, .while combining lightness with durability, shall permit of being more readily assembled and disassembled, than has been, so far as I am aware, heretofore possible.

It is, then, the fulfilment. of these two purposes which this invention has for an e'xpress obect, and toward theaccomplishment of whic it consists of means hereinafter fully described and particularly set forth in the claims. a ,b

The annexed drawings and the' followidg description set forth in detail certain mechanism embodying my invention, the disclosed means, however, constituting but one of vnrious mechanical forms in which the principle of the invention may be applied.

In said annexed drawings z-lf`igure 1 is a horizontal section of a differential gearing embodying my invention. Fig. 2 is a vertical section'on line II--Il of Fig. 1, lookingiin the direction of the arrows.

efcrring to the drawings in which like letters of reference rlcfer to like parts in both thel views, it will be noted that the structure in its entirety is supported in the usual manner from the frame A, shown in dotted'lines, and more specifically upon the ball bearings a., also shown in dotted lines. The structure comprises a easing member B rovided with a laterally projecting annuar fiaugeb, which is associated with the bearings a in the usual manner. This me|n ber is also provided with a longitudinally projecting annular flange b.

A primar driving gear C, 'which is driven by means o the usual driving pinion, shown in dotted lines, is adapted to rest against the annular flan e b'. A complementary housing member) is similarly provided witha An .is with the bolts c2 and nuts c.

` dat.

laterally projecting annular flan e c, and a longitudinally projecting flange c The latter is adapted to abut, in turn, the o posite sides of the primary gear C, wlierelby'the latter may be detachably sccuied between the Hongos b and c', in any approved man- A stud l-, having mounted upon it the two oppositely disposed idlers e, is connected to the housing member D by means of cap-screws e. These are, then, locked in the usual or any approved manner, as shown at c. idlers are,`pf course, in mesh, with two secondary driving gears l", whichare keyed to the ends of the two axles G, as indicated. They are held against displacement by the nuls g. The latter abut the stud E, as clearly appears in Fig. 1`

TheA` As will now be apparent to those skilled in the nrt, the-driving pinion operates to effect the rotation of the primary driving gear, which, in turn, rotates the liousin member D, to revolve the idlers e, whic finally rotate the secondary drivingr gears F, and so necessarily the axles. My invention is especially designed to facilitate the assemblage or dsussemblage of the inclosing parts, whereby the interior gear construe tion can be readily inspected or adjusted as the cxigencies of the ease may require. This muy be accomplished through the readily accessible agency of the nuts of and capscrews e'.

Having fully described my invention, what l claim and desireto secure by Letters Patent is:-

1.'1'n a differential gearing the combination of a housing member, a primary driving geur, a casino` member, means for detachably securing sai( ,driving member between said housing and casing members, a stud carried wholly by said housing member, said stud being of :i length equal to the diameter of said housing member, idlers mounted on said stud, axles extending into said housing member und abutting said stud, seconder driving gears upon said axle and in mes with said idlcrs, und detachable means for securing said stud to said housing member.

2. -In a differential gearing the combination of n housing member provided with ali annular flange, u primar driving gear, a complemcnlul casing mem )er provided with an annular Harige, means for curing said primary gear to said flanges, a, stud carried wholly b said housing member and of a length e ua to the diameter thereof, idlers carried y said stud, axles extending into said housing member, secondary drlvmg gears carried by said axles and in mesh with said idlers and cap screws extending through said housin the opposte ends of said stu Signed by me, this 26th day of JAMES G.
